flotation platinum schemes - vickybbedbreakfast.co.za
The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for the upgrading

Bulatovic [31] conducted a research study to evaluate alternative reagent schemes for the flotation of platinum group minerals from various ores. For the chromium-rich, highly oxidized ore from ...
Evaluation of alternative reagent schemes for the ...
In the past several years, research work has been carried out on a number of different ores containing platinum group elements (PGE), with the objective of developing alternative reagent schemes that would improve PGM recovery and concentrate grade in the operating plants.
Evaluation of alternative reagent schemes for the ...
Oct 01, 2003 · The floatability of chromium is also related to the flotation pH, whereby chromium flotation activity increases at higher pH values. 4.2. Flotation studies. Research work on this ore concentrated on finding a reagent scheme and operating conditions that would reduce the chromium content of the PGE concentrate and improve the PGE flotation rate.

The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of...
Recovery of PGMs from an oxide ore by flotation and leaching
flotation recoveries achieved using the sulphide co-collector schemes were 55.1% 3E (Pt, Pd and Au). Application of the hydroxamate oxide collector improved the flotation performance to recoveries of 74.7% 3E. The superior PGM recoveries achieved with hydroxamates probably lies in their ability to form complexes with metals such as iron.

The flotation plant of Karee Platinum Mine is especially suited for doing test work. It is well instrumented and has a modern PLC and Scada system which are vital for seeing what effect changes have on the plant and for collecting the necessary information. The plant has a Courier system for on-line analysis of a number of plant streams.
PGM extraction from oxidized ores using flotation and leaching
The maximum PGM flotation recovery achieved using sulphide co-collector schemes was 55.1% 3E (Pt, Pd, and Au). Application of the hydroxamate oxide collector improved the flotation recovery to 74.7% 3E. The superior PGM recoveries achieved with hydroxamates probably lies in their ability to form complexes with base metals such as iron.
